Going solar in the U.S. is easier and cheaper than ever, but many don’t make the investment because of the initial sticker price. However, the new fund will cover the upfront cost of solar panel installations, making it possible for thousands of people to switch to renewable energy.

According to a SolarCity blog post, once the panels are installed, the homeowner will then pay SolarCity for the electricity produced, or monthly rent if the panels are leased. This arrangement, the company notes, is the same kind most of us have with our local utility, except SolarCity’s power is usually cheaper and comes from the clean burning energy of the sun.

“We’re happy to support SolarCity’s mission to help families reduce their carbon footprint and energy costs,” said Sidd Mundra, renewable energy principal at Google. “It’s good for the environment, good for families and also makes good business sense.”

The new fund is the largest of its kind ever created for residential solar power, and the second such collaboration between the two companies. Back in 2011, the search giant invested $280 million to create a similar fund to help SolarCity put more panels on residential roofs.

According to Gigaom, Google’s investment with SolarCity can provide an 8 to 12 percent return on the investment. A SolarCity spokesperson told the website that the remaining $450 million of the $750 million fund will come from debt financing.
